7.2.8

Module type (NCK)

The type of PROFIsafe component cannot be explicitly specified. The F master
determines the type depending on the machine data in which a PROFIsafe
address has been entered:
S $MN_PROFISAFE_IN_ADDRESS
S $MN_PROFISAFE_OUT_ADDRESS
Dependent on this, the PROFIsafe component is identified as either input, output
or bidirectional I/O module.

7.2.9 Parameterizing the F master (PLC)
In the PLC, the F master does not have to be explicitly parameterized regarding
the connection of F modules.
The PLC is parameterized explicitly as follows:
S Parameterizing the NCK
S Generating and downloading the configuration
Data block DB18
Two bit arrays in data block DB 18 are used to display which INSEP/OUTSEP
bytes are only assigned to F modules as a result of the parameterization in the
NCK machine data:
S MD10388 $MN_PROFISAFE_IN_ASSIGN
S MD10389 $MN_PROFISAFE_OUT_ASSIGN
only F modules are assigned.
